    1. INTRODUCTION The CEC7 control unit is an electric network signal supervision device and conducts supervision and control of power supply through the generator set. The control unit consists of 2 different modules: • Display module. The display module is responsible for carrying out the information tasks regarding the status of the device and allows actions to be performed by the user;...

The different levels of access are as follows: • User (default password: 1111). User level access allows the operator to access the main menu of the CEC7 control unit.

  • Page 8: Operating Modes

    3. OPERATING MODES 3.1 MANUAL MODE In manual mode, the control unit is commanded by the user via the front panel of the display module. The user can start and stop the engine by pressing the START and STOP keys respectively. Pressing the START key initiates the engine starting procedure (without deactivating the network contactor).
  • Page 9 Furthermore, activation of the network and genset contactors is performed by 3.4 LOCKED MODE pressing the RED/MAINS and GROUP/GEN keys. In Lock mode , the control unit disables the genset startup under any condition. 3.5 AUTOMATIC MODE LOCK In order to achieve activation of the genset contactor, the engine has to be Pressing the AUTO or MAN keys for 5 seconds activates the mode lock.

    The integrated control mode on the generator set is programmed in the CEC7 control unit (Regulations table, parameter 30, values 0 and 1).
  • Page 11 The genset signal drop condition causes the genset contactor to open. The external control mode on the generator set is programmed in the CEC7 con- trol unit (Regulations table, parameter 30, value 3).

    3. Start-up of the generator set. The CEC7 control unit commands the start-up of the generator set: • Via the LT breaker in CEC7 control units con gured in external mode. • Via the communications bus in CEC7 control units con gured in integrated mode with CEM7 control units.

In this way, upon the return of the network via the Second Zero (SZ7) expansion.
  • Page 15 5.8 TIMER. The CEC7 control unit has a timer that tells the control device the current time and date. This device allows the weekly programming of: • Scheduled start-ups. • Scheduled locks. • Scheduled engine tests and maintenance. • Energy counters (day, month, year).

    (Times table, parameters 22 to 24) which requires that the value of the input is stable over a time interval. Also, the CEC7 control unit's inputs can be con gured to be active with contact closed to earth or be inactive with contact closed to earth (Regulations table parameters 11 to 14).
  • Page 17 Enabling of genset contactor activation (HKG) This function is only managed in automatic mode of the CEC7 control unit. The input con gured as enabling genset contactor activation (Settings table, parameter 8) inhibits the activation of the genset contactor until the input is active after stabilization of the genset electrical signal.
